Niccolo I d'Este

Niccolo I d'Este (1292-1343) was the lord of Ferrara from 1317 to 1343, succeeding Aldobrandino II d'Este and preceding Obizzo III d'Este.

Biography
Niccolo was a son of Aldobrandino II d'Este and a brother of Obizzo III d'Este, Rinaldo d'Este, and Bertoldo d'Este. In 1317, Aldobrandino ruled Modena and Reggio while his sons ruled Ferrara, and in 1326 they inherited Modena and Reggio after their father's death. In 1335, Modena fell and was recaptured, but Reggio was lost to the House of Este's enemies; Niccolo would rule Ferrara and Modena jointly with his brothers until 1343.
